# Anthropic Multi-Environment Setup

## Overview
Use different API keys, models, and limits across dev/staging/prod.

## Environment Configuration
```typescript
// config/anthropic.ts
interface AnthropicConfig {
  apiKey: string;
  model: string;
  maxTokens: number;
  maxRetries: number;
}

const configs: Record<string, AnthropicConfig> = {
  development: {
    apiKey: process.env.ANTHROPIC_API_KEY!,
    model: 'claude-haiku-4-5-20251001', // Cheap for dev
    maxTokens: 256,
    maxRetries: 1,
  },
  staging: {
    apiKey: process.env.ANTHROPIC_API_KEY!,
    model: 'claude-sonnet-4-20250514',
    maxTokens: 1024,
    maxRetries: 2,
  },
  production: {
    apiKey: process.env.ANTHROPIC_API_KEY!,
    model: 'claude-sonnet-4-20250514',
    maxTokens: 4096,
    maxRetries: 3,
  },
};

export const config = configs[process.env.NODE_ENV || 'development'];
```

## Separate API Keys Per Environment
Use different Anthropic API keys for each environment:
- **Dev key**: Low tier, spending alerts at $10
- **Staging key**: Medium tier, spending alerts at $50
- **Prod key**: Highest tier, spending alerts at usage baseline + 50%

```bash
# .env.development
ANTHROPIC_API_KEY=sk-ant-dev-...

# .env.staging
ANTHROPIC_API_KEY=sk-ant-staging-...

# .env.production
ANTHROPIC_API_KEY=sk-ant-prod-...
```

## Model Selection Strategy
| Environment | Model | Why |
|-------------|-------|-----|
| Development | Haiku | Fast iteration, cheap |
| Staging | Sonnet | Match prod quality |
| Production | Sonnet (default) | Balanced cost/quality |
| Production (complex) | Opus | Complex reasoning tasks |

## Output
- Environment-specific Anthropic configuration (model, maxTokens, maxRetries)
- Separate API keys per environment with appropriate tier limits
- Spending alerts configured per environment
- Dev using Haiku (cheap), staging matching prod (Sonnet), prod using Sonnet/Opus

## Error Handling
| Error | Cause | Solution |
|-------|-------|----------|
| API Error | Check error type and status code | See `clade-common-errors` |

## Examples
See Environment Configuration TypeScript pattern, API key separation strategy, and Model Selection Strategy table above.

## Next Steps
See `clade-observability` for monitoring across environments.

## Prerequisites
- Completed `clade-install-auth`
- Multiple environments (dev/staging/prod) configured
- Separate Anthropic API keys created per environment

## Instructions

### Step 1: Review the patterns below
Each section contains production-ready code examples. Copy and adapt them to your use case.

### Step 2: Apply to your codebase
Integrate the patterns that match your requirements. Test each change individually.

### Step 3: Verify
Run your test suite to confirm the integration works correctly.
